BASE FOR FENCE-POSTS.

SPECIFICATION forming part of Letters Patent No..405,445, dated June 18,1889.

Application filed November 30, 188B- Serial No. 292,189. (No model.)

To all whom it may concern/ Be it known that I, WILLIAM H. THOMSON, ofthe city, county, and State of New York, have invented a new andImproved Base for Fence-Posts, of which the following is a full, clear,and exact description.

This invention relates to fence-post supports, and has particularreference to that class of fence-post supports in which a felicepostbase is employed which is stiffened and held in place by detachablecross stakes or pins inserted through the base and driven into theground.

The invention has for its object to provide a fenceepost base havingdetachable anchor cross-pins which will project laterally from the baseinto the ground and interlock each other, thereby preventing them frombeing displaced and rmly holding the base in position.

The invention consists in a fence-post base having detachableinterlocking anchor crosspins constructed and arranged as hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar gures of reference indicatecorresponding parts in all t-he views.

Figure 1 is an elevation of the fence-post base in position forsupporting a post, with a portion of the anchorpins in cross-section-Fig. 2 is a vertical section thereof on the line o; x, Fig. 1, with aportion of the anchor-pins broken away and a portion in section. Fig. 3is a plan view of the invention, with the post in horizontal section onthe line .z z, Fig. 2. Fig. 4 is a detail of the invention, shoving basebroken away and one of the anchorpins slightly drawn out of the base.Fig. 5 is a horizontal section of the invention on the line y y, Fig. 2.Fig. G is a perspective view of the invention, showing the base brokenaway and the anchor-pins in interlocked po sition. In the constructionof the invention the base may be of any suitable form, either angular orround, of cast or wrought metal, in a single piece or in sectionsfastened together, and preferably formed with a pointed or taperinglower ond, whereby it may be driven into the ground.

As here shown, the base 1 is formed with sides 2,ihe tapering lower end3,and asocket 4 at its upper end, which may loe of any desired shape toreceive the lower end of a fencepost- 5. The base 1 is also formed withan internal chamber or cavity G, having inclined opposite aligningopenings 7 8 9 10 irregularly placed in its walls for the interlockinganchor-pins 7, 8', 9', and 10 to extend through in adownwardly-inclineddirection crosswise to each other. i

The pins 7, 8', 9, and 10 are of flat shape, with pointed ends 11, so asto readily enter the ground, and are formed with suitable heads. Asshown, they are formed with square heads 12, which rest in countersunkrecesses 13 in thc sides of the base, the recesses 13 havingnotches 14in their edges, by means of which the heads 12 may be grasped with atool to pull the anchor-pins out of their slots. The opposite aligningopenings 7 8 9 10 are located in the upper part of the .base 1, so thata sufficient length of the base extends beneath t-he openings to bedriven into the ground.

In securing the base 1 in the ground it is driven into the same untilthe upper opening of the openings S is about even with the surface ofthe ground and the lower openings 7 and S are beneath the surface, asshown in Fig. 1. The pins 7 3 0 10 are inserted through their openingsin regular order to interlock each other, the pin 7 being first insertedthrough its openings 7 and driven into the ground until its head 12enters its recess 13. The pin 8' is then passed through its upperopening S, through an opening 15 in pin 7', through its lower opening 8,and driven into the ground until its head 12 enters its recess 13. Thepin 9 is then inserted through its openings 9 and driven into thelground until iis head 12 enters its recess 13', and, lastly, the pin 10is passed through its upperbpening 10, through an opening 16 in pin 9',through its lower opening 10, and driven into the ground until its head12 enters its recess 13.

By means of the foregoingdescribed arrangement of interlockinganchonpins the base 1 will be held firmly in the ground and will remainsteady in upright position, so as to prevent the post from sagging ortipping. The anchor-pins cannot become separately IOO loosened ordisplaced, as, being interlocked, they must move together. Theanchor-pin 10, last inserted, may be secured in place by any suitablemeans. As here shown, it is fastened by means of a pin 17 passingthrough a hole 18 therein and extending on each side of the lower slot10 adjacent to base 1. In order that the pin 10 may clear the pins 7 and8', the pin 7 is formed with a notch 19 on one edge thereof and the pinS with a notch 2O on one edge thereof. lVhen the anchor-pins are inposition, the pins 7 and S will be concealed in the base 1 and beneaththe ground, and a portion of the pins 9 and 10 will appear above theground.

To remove the base, the pins 7 8 9 10 are drawn out in the reverse orderfrom that in which they were put into place, the pin 17 being removedfrom pin 10 and the latter withdrawn from place, and so on insuccession, ending with pin 7 when the base 1 may be pulled up. lt willthus be seen that the base 1 may be readily secured in the ground bydriving it without iirst having to excavate a hole and then securing theanchor-pins in place, thereby affording a firm and stable fence-postbase.

It is obvious that any number of anchorpins desired may be employed, andthat they may be made round instead of fiat. The base 1 may be also madewith any number of sides.

While I have described a specific construction of parts, I do not desireto limit myself thereto, as the parts may vary in detail withoutdeparting from the essential features of the invention.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is-

l. A fence-post base formed with a point to enter the ground and havingdetachable interlocking anchor-pins extending crosswise thereto andadapted to enter the ground, substantially as shown and described.

2. A fencepost base formed with openings irregularly located therein, incombination with interlocking anchor-pins which extend through theopenings and project laterally from the base, substantially as shown anddescribed.

3. A fence-post base formed with openings irregularly located therein,in combination with interlocking anchor-pins which extend through theopenings and project at an incline downward from the base, theanchorpins being inserted through the base in regular order to interlockeach other, with means for fastening in place the pins last inserted,substantially as shown and described.

4E. ln a fence-post base, substantially as described, the base 1, formedwith internal chamber (i, the inclined aligning opposite openings 7 S 910 in the walls of chamber 6, a fencepost socket 4 at its top, and atapering lower end 3, substantially as shown and described.

5. A fence-post base 1, formed with internal chamber 6, the inclinedaligning opposite openings 7 8 9 l() in the walls of chamber (5, afence-post socket 4 at its upper end and the tapering point 3 at itslower end, the upper openings 7 S 9 10 having countersunk recesses 1S,with notches 14 in their edges, in

pins 7, S', 9', and 10, having heads 12, fitting recesses 13, andinserted in regular order through openings 7 S 9 10, respectively, tointerlock each other, the pins 7 and 9 having openings 15 and 16 for thepassage of pins S VILLIAM H. THOMSON.
